How long does it usually take for brain cancer to go from early stage to late stage

If it is found in the early stage, it should be treated early to prevent the disease. Some cancer cells grow slowly and will not appear until the end of life. Some cancer cells grow very fast and develop into cancer in a short time, such as choriocarcinoma and small cell lung cancer. If the treatment is not timely, it will grow very fast. The prognosis of brain tumors in the early stage is good, and the life span can be the same as that of ordinary people, and it will not affect life. However, the cure rate in the late stage is very low, and the survival time ranges from one to three years. It takes some time for brain cancer to go from the early stage to the late stage, and the time is uncertain, which also depends on each person's condition.

How effective is whole brain radiotherapy for brain metastases?

Whole-brain radiotherapy has a better control effect on brain metastases, because radiotherapy can penetrate the cerebrospinal fluid barrier and the blood-brain barrier, reach the tumor tissue in the brain, kill tumor cells, and control tumor growth. Whole-brain radiotherapy has a better control effect on brain metastases, because radiotherapy can penetrate the cerebrospinal fluid barrier and the blood-brain barrier, reach the tumor tissue in the brain, kill tumor cells, and control tumor growth. In addition, if it is a single lesion, stereotactic radiotherapy, that is, gamma knife and other treatment methods can be used to control brain metastases.
